Remember those leaked Windows Vista Pre-SP1 updates that I said I wasn't going to link to? Well, today they were officially released by Microsoft. They contain a ton of fixes that improve Vista in a number of areas. You can get them here:

Certainly seems to improve network file copy speed. Before I applied them, performance was pathetic, managing to get around 30MBit on a 100MBit LAN copy files from one Vista box to another. It's now maxing out the 100MBit connection completely

Oh yes, they're very reliable... in destroying your Windows installation that is. I thought I'd try the performance update, knowing that I could roll back using System Restore. But who am I kidding? After a reboot, Windows wouldn't start again because winlogon.exe was "corrupted" or something. Had to reinstall Windows. Way to go, Microsoft.
